Origineelreclamebord & OneKiwi
I've got an 87/24, SP esc & frsky rx. Standard alloy chassis.
I just took the pinion off & moved the motor all the way to the rear - virtually no difference in weight distribution (3g more on rear with 3g less on front).
Interestingly it seems as if I've got more weight on the rear than OneKiwi - I made both the shorty / saddles at ~60% rear from the pics & the overall weight is about 70g more than my 210 - so I could start to play with this much weight, pretty sure I'd get close to 65% if I did. Wheelbase is obviously different.
I do weigh then slightly differently - see pic, not sure if this has any affect.
